Abstract

A system for electrical power generation uses the movement of the tides to drive paddle wheels or turbines 6, 7, 8. The turbines are provided in sea walls or dams between points 2 and 3, 4 and 5, which separate sea basins 10, 11 from the rest of the sea. The movement of water is controlled so that there is a continuous flow in the system.

Description

The objct of this invevtion is to obtain elctrical power from the movement of the tides. But

this invention shows how we continue to get power at high and low water when the movement of the tide is niL There would be absolutly no pollution and no fuel costs. It could be developed on almost any coast line, stop coastal erosion and once developed it would be cost free forever except for mentainance.

Fig 1. shows a coastal inlet cove, or bay. From point 2 to 3 is built a sea wall or damm. From 4 to 5 is built a ilt a stronger one. Part 9 is a lock with gates 12 and 13 at tieher end for navigation. Part 6, 7 and 8 are paddle wheels or turbins.

When the tide is rising part 6 will rotate and generate electricity. Sea basin 11 is isolated from this t by parts 7 and 8. When the water flows slowly as high t approaches parts 8 and or 7 can be activated At high tide part 6 is sealed to separate sea basin 10 from the lake river,sea or ocean.

When the tide has receded enough part 6 can be re-started and part 8 sealed, part 6 is now turning in the opposite direction but this can be overcome by using a reverse gear, changing the polarity of the generator or by rotating it 180 degrees horizontally. At low tide part 7 is sealed after sea basin 11 is empty. As the tide rises parts 7 and 8 are rar < f aHdaf < ! Mo/ < ' < t Wtt < A < s < tdc has risen enough part 6 is started and parts 8 and 7 sealed to keep the water in sea basin I I lawfor the transfer of water from basin 10 at high tide through part 8 or from the sea at part 7. Now the cycle is complete.

Claims

Untitled CLAIMS A system of controlling tides so there is water movement twenty four A day every day A system of controlling tides as claimed in claim 1 where sea walls or damms are used to keep part of the tide at a different level to the rest of the tide thus having continuous movement of water <Desc/Clms Page number 3> Amendments to the claims have been filed as follows Claims

1 1. A tidal pumped storage power generation arrangement, comprising first and second basins, the first basin being vulnerable to tides and the second basin being sealed, both of said basins having at least one electrical power generation means associated therewith, whereby the electrical power generation means associated with said first basin is arranged to operate while the tide is rising or falling, the arrangement further comprising means for causing water to flow directly from said first basin into said second basin around high tide, and means for causing water to flow directly from said second basin into said first basin around low tide, such that the electrical power generation means associated with said second basin operates around high and low tide.

2. An arrangement according to claim 1, wherein the first and second basins are defined by two sea walls or dams.

3. An arrangement according to claim 2, wherein a first sea wall or dam is provided between two land points or similar permanent fixtures, and a second sea wall or dam is provided between a point on said first sea wall or dam and a third land point or similar permanent fixture.

4. An arrangement according to any one of the preceding claims, wherein electrical power generation means, such as a turbine or paddle wheel, is provided between the first basin and a tidal body of water in which the arrangement is to be operated, between the second basin and the same tidal body of water, and between the first and second basins.

5. An arrangement according to any one of the preceding claims, wherein a lock is provided between the first basin and a tidal body of water to enable access between the two by a vessel or the like.

6. An arrangement according to claim 4, wherein as the tide rises, the electrical power generation means between the tidal body of water and the first basin is activated.

7. An arrangement according to claim 6, wherein the other two electrical power generation means are sealed as the tide rises.

8. An arrangement according to claim 7, when the flow of water becomes relatively slow, around high tide, one or both of the electrical power generation means between the first and second basins and between the second basin and the tidal body of water is/are activated, and water caused to flow from the first basin into the second basin.

9. An arrangement according to claim 8, wherein at high tide, the electrical power generation means between the first basin and the tidal body of water is sealed, and water continues to flow from the first basin into the second basin through the associated electrical power generation means.

10. An arrangement according to claim 9, wherein water is caused to flow from the second basin into the tidal body of water through the associated electrical power generation means.

11. An arrangement according to claim 10, wherein as the tide falls, the electrical power generation means between the first basin and the tidal body of water is activated and the other two electrical power generation means are sealed.

12. An arrangement according to claim 11, wherein when the flow of water becomes relatively slow, around low tide, one or both of the electrical power generation means between the first and second basins and between the second basin and the tidal body of water is/are once again activated.

13. An arrangement according to claim 12, wherein at low tide, the electrical power generation means between the first basin and the tidal body of water is sealed, and water is caused to flow from the second basin into the tidal body of water through the associated electrical power generation means.

14. A tidal pumped storage power generation arrangement substantially as herein described with reference to the accompanying drawings.

15. A method of electrical power generation, comprising the steps of providing or creating first an second basins, the first basin being vulnerable to tides and the second basin being sealed, providing respective electrical power generation means for operation in association with each of said basins, causing the electrical power generation means associated with said first basin to operate while the tide is rising or falling, causing water to flow directly from said first basin into said second basin around high tide, and causing water to flow directly from said second basin into said first basin around low tide, thereby causing the electrical power generation means associated with said second basin to operate around high and low tide.

16. A method of electrical power generation substantially as herein described with reference to the accompanying drawings.
